UGears Marble Run Chain Hoist model kit 3D puzzle 400 pcs

The UGears Marble Run Chain Hoist model kit is a 3D wooden puzzle consisting of 400 laser-cut parts that assembles into a functional marble run with a hand-cranked chain hoist. The finished model lifts marbles to the top where a three-way distributor sends them along different tracks: a chute with a loop-the-loop, cascading stages, and short tracks fed from an accumulator. The kit is modular and can be connected to other Marble Run Chain Hoists using the included connectors to build a small system of runs and hoists. The set includes pre-cut wooden boards, 10 marbles, wax, sandpaper and illustrated instructions in multiple languages. The assembled model measures approximately 275 mm wide and 270 mm high and is rated as a medium difficulty build with an estimated assembly time of 7 hours.

Advantages

This mechanical marble run combines kinetic sculpture and educational engineering, demonstrating gear and chain hoist mechanics in a hands-on way. The laser-cut wooden parts snap together without glue or special tools, and spare parts are included; additional individual replacements are available from customer service. The modular connectors allow two or four units to be joined for expanded configurations. The kit provides everything needed for assembly, including marbles, wax, and sandpaper to ensure optimal gear operation.

Suitable for

• Hobbyists interested in mechanical models and 3D puzzles
• STEM learning and demonstrating basic mechanical principles
• Family projects and shared DIY assembly for ages 14 and up
• Decorative desktop kinetic sculpture for home or office

How to use

Remove the pre-cut parts from the laser boards and follow the detailed illustrated instructions to snap components together in sequence. Use the provided sandpaper and wax on gear contacts where indicated to ensure smooth rotation and reliable chain hoist operation. Turn the hand crank clockwise to operate the wooden chain hoist; marbles will be carried to the top, distributed by the three-way switch, travel along the selected tracks and return to the collector tray to begin a new cycle.

Usage recommendations

Assemble on a flat, stable surface and keep small parts and marbles away from young children. If a part breaks during assembly, use the included spare pieces or contact customer service for a replacement part. Periodically apply the supplied wax to gear teeth and contact surfaces for consistent performance.
